Description
The following are the main findings: (1) Fragments with typically
1021Mx preserve their identity and even survive to the decay
of the sunspots. (2) Each fragment has a very precise location in the
whole ensemble. (3) The incomplete coalescense of the fragments leaves
interstices which are penetrated by hot gas. This gives a natural
explanation of the umbral fine structures (ie. umbral dots and light
bridges).
